“Coldplay: A Head Full of Dreams” is a movie both fans and haters will appreciate

“Coldplay: A Head Full of Dreams” is so charming and sincere that it will make you feel bad about mocking the band’s music for the last 16 years (aside from intermittent appreciation for what Brian Eno got out of them on “Viva La Vida,” of course).

Mat Whitecross’ film is more than just a look inside the third-highest grossing concert tour in history, or an intimate portrait of one of the 21st century’s most successful rock bands; it’s also an infectiously upbeat biography of four blessed friends (five, if you count their manager; six if you count Whitecross himself), who conquered the world on the strength of their belief in themselves and each other.

In other words, this feature-length victory lap should be utterly insufferable from start to finish. It isn’t.
